Liv Attacca TT Helmet

Hit your performance potential for triathlon or time trials. Front to back, every curve and shape of the Attacca TT is fine-tuned through Computational Fluid Dynamics for optimal aerodynamics. Wind tunnel tests prove that it provides an aerodynamic advantage in various rider positions and at different wind angles. And on the road, Attacca TT delivers unrivaled fit and comfort for Team Sunweb pros and everyday competitors.



  • Designed specifically for pure competitive advantage in triathlon and TT, where the smallest gain in aerodynamics is critical
  • Maximum ventilation through front vents ideally positioned to puncture the airflow and direct it through ultra-deep internal channels
